Problems solved by technology

[0003] The temperature of the lubricating oil is generally not too high during normal driving. When the vehicle is overloaded or the four-wheel drive mode is set to drive on snow or off-road, the vehicle is driving under the condition of excessive slippage of the hydraulic torque converter, which may cause gear shifting. Oil temperature is too high, thus losing lubricating properties

specific Embodiment approach

[0031] The orientation nouns such as top, bottom, left, and right described in the present invention are all described according to the relationship between up, down, left, and right in the accompanying drawings;

[0032] The above definitions are applicable in all statements herein, and will not be repeated hereafter.

[0033] Such as Figure 1 to Figure 3 The embodiment of the thermostat shown: the thermostat includes a valve body 102 with a cavity 112 and a thermodynamic element fitted in the cavity 112. The thermodynamic element includes a body 204 containing a thermosensitive substance and a sliding installation The ejector rod 205 at the first end of the body 204, one end of the ejector rod 205 is exposed outside the body 204, and the valve body 102 also includes three interfaces respectively communicated with the cavity 112: the first interface 104, the second interface 105 and the third interface 106 , when the thermal element is heated, the heat-sensitive substance e...

Embodiment 2

[0041]The biggest difference between embodiment 2 and embodiment 3 is that the valve body of the thermostat of embodiment 2 is provided with a flow channel communicating with the third interface 106 . However, the third interface 106 of the thermostat valve body in Embodiment 3 needs to be externally connected to pipes connected to other devices. Secondly, the dimensions of the chamfers around the end portion of the second end of the body 204 are also different.

[0042] In the above embodiment, when the thermal element is heated, the thermal element of the thermostat moves toward the third interface 106 and slides in the third interface 106 to block the third interface.

Abstract

The invention relates to a thermostat for a heat exchange loop. The thermostat for the heat exchange loop comprises a valve body provided with a cavity, and a thermal actuator arranged in the cavity in a matching way; the valve body also comprises two through holes including a first hole and a second hole which are respectively communicated with the cavity; the first ends of the second hole and the first hole are respectively communicated with an inlet and an outlet of an external fluid cooling device; the second ends of the second hole and the first hole are respectively a fluid inlet and a fluid outlet; the inner diameter of the cavity is larger than that of the second hole, and the cavity is communicated with the second hole; the end of the cavity close to the second hole is coincided with part of the second hole; an elastic part is sheathed at the peripheral side of the thermal actuator; one end of the elastic part leans against and is connected with the thermal actuator in a pressing way, and the other end of the elastic part leans against and is connected with a shoulder part formed by the bottom of the cavity and the second hole in a pressing way. After the thermostat for the heat exchange loop is adopted, the working temperature of lubricating oil is controlled to be within the effective range, and the lubricating property of the lubricating oil is maintained in the best state.

Description

technical field [0001] The invention relates to the mechanical field, and more specifically, relates to a thermostat for a heat exchange circuit. Background technique [0002] During the driving process of the car, lubricating oil needs to be replenished in time to ensure the normal operation of the car. If the lubrication performance of the lubricating oil is not good enough, it will greatly reduce the service life of the car and even cause a car accident. The lubricating performance of lubricating oil is closely related to its own temperature. When the temperature of lubricating oil is too high or too low, the lubricating oil will lose its lubricating performance. [0003] The temperature of the lubricating oil is generally not too high during normal driving. When the vehicle is overloaded or the four-wheel drive mode is set to drive on snow or off-road, the vehicle is driving under the condition of excessive slippage of the hydraulic torque converter, which may cause gea...
